Materials needed
4’ piece of rebar to stir the concrete in the post holes, 1x3 x8’ strapping to stabilize posts during
concrete curing (used strapping for braces and for stakes), and 12 sheetrock screws for braces,
post hole digger, shovel, level, tape measure, 80 lb bags of premixed concrete (not included).

.
Amount required depends on how deep you dig the holes.
1) Keep in mind that this is a climbing element and therefore should have a fall zone
extending 6 feet out on all sides of it which is usually 6-12” deep. You can create an
above ground container for this material by using either 2 layers of 6x6 retainers
made for this purpose (which are for sale in another section in this store), or by
digging a large hole 12” deep. If you choose to dig the hole, keep in mind that it
needs to be drained so it doesn’t fill up with rainwater or snow melt.
2) If you decided to use a fall zone, don’t Install the fall zone material until you have dug
the holes for the posts, and installed the posts.
3) Stretch out the climbing net in the area in which it’s going to be mounted, making
sure the ropes are straight all the way across the circle and beyond.
4) Leave at least 24 inches between the edge of the net and the front side of where the
posts will be, and mark all 8 post locations. You need this space to tighten the ropes if
they get loose.
5) Dig all eight post holes as deep as required in your region, keeping in mind that the
post has to go up through fall zone material, and that the top hole on the posts should
be at least 24-36 inches off that material. With weight on it, the net will sag, so you
need clearance.
6) Some people like to tilt the posts slightly away from the net, so if you want to do that,
adjust the holes accordingly.
7) If you choose to use 12 inch to 14 inch Sonotubes, make any further adjustments to
the hole so that these tubes drop in cleanly. But then you MUST backfill and compact
around the Sonotubes. KEEP IN MIND that if the earth is disturbed, you will end up
with loose posts, so sometimes it’s better to just dig the holes, and use the earth as
the container (no sonotubes).
8) Mark the desired depth of the posts on each post so you can try to keep the tops
level (unless you are sloping the net, in which case you might need longer posts, or
you might need to add extensions to the posts that came with the package).
9) Put about 6 inches of drainage stone at the bottom of each hole.
10) Drop the posts into the holes, and use more or less drainage stone to adjust the
post heights to where you want them.
